Usrey works at the Tennessee National Guard headquarters in Knoxville, Tennessee. The photo was captured in Vine Grove, Kentucky, near Fort Knox; it was taken by Instagram user Erin Hester earlier this month and promptly went viral.

“I was so completely touched by this today,” she wrote. “I feel pretty confident there isn’t a military rule that soldiers have to do this. This made my heart happy to see the amount of respect that this gentleman showed a family that he doesn’t even know.”

Usrey is one of many in his family to have served, reports WSMV. His father and brother served in the Navy, with his brother advancing to the rank of lieutenant colonel. One of Usrey’s sons serves in the Navy now, and another is a student at The Citadel.
